I have been thinking about the timing of this contract too.
1st, they have been deliberately 'saving' it for the 2H reporting to neutralise the sheet results.
2nd, it's a perfect cover up for any possible inside trade, recall that 1.7m volume jump right before 2H was released? While everyone panicked and were rushing out, someone on the other side of table is brave and 'clever' enough to take a risky punt.
But you can't prove anything, they can argue it's perfectly normal for the volume to spike before reporting, ASX wouldn't have solid ground to demand explanation further.
What a smart but dodgy timing it was...
